What is a Multispectral camera agriculture. A Multispectral camera agriculture sensor captures multiple images in the ultraviolet visible and infrared ranges. It allows professional farmers to manage crops, yields, fertilizing and irrigation more effectively. Each of the images taken with a Multispectral camera for precision agriculture is passed through a filter to restrict light to a specific color or wavelength.There are huge benefits of Multispectral sensors for both to the farmer and to the wider environment by minimizing the use of pesticides, fertilizers, wastage of water and at the same time increasing the yields at harvest time.
How does a Multispectral camera agriculture work in order to understand Multispectral camera technology. It is useful to consider first how monochrome and color. Cameras work a monochrome. Camera contains an image sensor which is comprised of a two-dimensional array of light-sensitive pixels. These pixels are sensitive to incoming light across a broad spectral range for example in a monochrome CMOS image sensor. Each pixel is sensitive to light from 400 nanometers to 1,000 nanometers covering visible and NIR ranges a monochrome image sensor captures light at all. Wavelengths and hence cannot discriminate between different colors and wavelengths of light. The images are black and white like a monochrome camera. A color camera contains an image sensor with a two-dimensional array of pixels however in a color camera. The multispectral camera remote sensing is coated with a mosaic arrangement of pigments that transmit red, green or blue. These pigments make up what is called the Color Filter Array (CFA) well-known from common RGB cameras. A Multispectral camera remote sensing imaging technology is one that captures image data within specific wavelength ranges across that uses Green, Red, Red-Edge and Near Infrared wavebands to reflect both visible and invisible images of crops and vegetation. The Multispectral images integrate with specialized agriculture software which output the information into meaningful data.
A raw image captured with a color camera can be thought of as three separate images which when recombined through a debayering process form a familiar color image. Spectral imaging devices typically employ similar principles for generating Multispectral images. However, patterning pigments representing red and blue colors on the image sensor spectral devices pattern the sensor with micro sized optical filters that have tunable color and transmission characteristics. A raw image captured with a Multispectral camera agriculture can be thought of as four separate images each taken at a specific wavelength with well-defined bandwidth for example an RGB-NIR multispectral camera. It has red, green, blue, and NIR bands. The RGB mono Multispectral camera has red, green, blue, and pan chromatic bands. Spectral devices Multispectral camera for precision agriculture has yellow, red, red-edge and NIR bands.
This farm telemetry data allow the professional farmers to monitor, plan and manage the farm more effectively saving time and money along with reducing the use of pesticides. In addition to, the benefits of implementing telemetry in farm is to remotely monitor water points on large-scale cattle properties.

Benefits of Multispectral Imaging Using Drones in Agriculture Sectors
The technology Multispectral images are a very effective tool for evaluating soil productivity and analyzing or detecting plant health both with stations positioned at fixed points in particularly delicate areas, or with mobile devices mounted on unmanned air vehicles (UAVs), commonly known as a drone. Surveying the health of soil, crops and livestocks with drones, you can obtain a high spatial detail of the information, different with the naked eye, you will get very limited information. A Multispectral sensor technology allows the farmer to see further than the naked eye, coupled with the enormous speed acquisition in analysis of the data.
